\(यदि (A={x:x\) का गुणज 4 है\(, 1\le x\le 25}) और (B={x:x\) का गुणज 6 है\(, 1\le x\le 25}), तो (A\cup B) में कितने अवयव हैं\)?

\(If (A={x:x\) is a multiple of \(4, 1\le x\le 25}) and (B={x:x\) is a multiple of \(6, 1\le x\le 25}), how many elements are in (A\cup B)\)?

Explanation opens after your attempt
Correct Answer

B. (9)

Step 1

Concept

\(A=\{4,8,12,16,20,24\}\) and \(B=\{6,12,18,24\}\). The union has (9) distinct elements.

Step 2

Why this answer is correct

The correct answer is B. (9). \(A=\{4,8,12,16,20,24\}\) and \(B=\{6,12,18,24\}\). The union has (9) distinct elements.

Step 3

Exam Tip

\(A=\{4,8,12,16,20,24\}\) और \(B=\{6,12,18,24\}\) है। संघ में (9) अलग अवयव हैं।
